Dropbox accessing random files

Hello,
so yesterday I thought it would be a good idea to monitor what files get accessed with procmon.
So I found out that Dropbox.exe accesses random files that don’t belong to it while my PC is idleing.
It’s mostly just reading the file attributes, I guess to enumerate all files existing on my system.
Here is a complete list of all files it accessed, sorted by the access count, top is the most accessed:

"C:\Users\pfannkuchen\AppData\Roaming\Dropbox\PENDING_zaqeyg"

Any idea what the heck it’s doing? The Folder it’s configured to sync is D :\Dropbox

EDIT: someone on another forum gave me a link which quoted an answer from Dropbox support, in which they state that it’s just checking the files if they are synced to determine if the little sync icon needs to be drawn. That sounds logical, but still is a little strange that it checks all files, no matter if they’re in the dropbox folder or not.
